PULSE VOLTAGE GENERATING CIRCUIT, DISCHARGE CIRCUIT, AND EMISSION ANALYZER USING THE CIRCUITS

摘要

Disclosed is a pulse voltage generating circuit which is provided with: a transformer (1) having a primary winding and a secondary winding; a snubber capacitor (21) connected in parallel to the primary winding; an excitation capacitor (3) which supplies the primary winding with an excitation current; a switching element (6) which is inserted into an excitation current path through which the excitation capacitor (3) supplies the primary winding with the excitation current; and a load capacitor (4) which is connected in parallel to the secondary winding. The relationships among the capacity of the snubber capacitor (21), the capacity of the load capacitor (4), the floating capacity of the secondary winding, the inductance of the primary winding, the excitation inductance of the transformer (1) and the winding ratio of the transformer (1) are adjusted such that the first peak value of the voltage between the both ends of the load capacitor (4) after the switching element (6) is turned off is higher than the second and the subsequent peak values.
